Construct a population pyramid for your selected county (for the most
recent date for which data is available),
interpret this age/sex structure, possibly by comparing it
with that of Washington State or the United States, identify any
peculiarities you may find, and, if appropriate, briefly discuss the
significance of your county's age/sex structure for your topical
interests.

You may submit your pyramid on paper or on your Website. For the latter,
you may want to use the Washington
State Pyramid as a template [I suggest that you multiply the
equivalent values by at least 10].

Pyramid Building
The purpose of this lesson is to provide students with the background to
understand the importance of age structure on population growth. They do
this by creating a population pyramid. This process will also help them
understand the meaning of different shaped "pyramids" and the impacts of
these different growth patterns.

Population Pyramids and Us [National Geographic]
Overview:
When geographers want to examine the population of a given area, they may
employ maps to help them see distribution patterns or employ photographs
to analyze cultural activities. When geographers want to examine the
structure of a population and the potential for growth in that
population,...

Animated, 1971-2005
The population pyramids presented here are animated to show the change in
population distribution for Canada, the provinces and territories from
1971 to 2005. The data are standardized and expressed as a number per
100,000 population, allowing comparisons between regions of different
sizes. To view the animated population pyramids, select the name of the
region you wish to view...

Building Communities for Tomorrow (Iowa)
A population pyramid graphically displays the age by sex data of a
community at one point in time. The graph helps to easily
see the age distribution of both males and females at a glance. By
comparing population pyramids from various years (for
example, past, present, projected) it is easy to see changes in the age
structure of a community's population. It is also a very
visual way to compare the community you are studying to another community
to the state.

Michigan, 1900, 1930, 1960, 1990, 2020 (fig 1 & 2)
"Population pyramids show the relative size of each age and sex
category. The youngest age group is at the bottom and the oldest is at the
top; males are on the left and females are on the right. The
pyramids in
Figure 1 are drawn to a uniform scale in order to illustrate the
growth in
the size of the population. The distance between each vertical line in
Figure 1 represents 100,000 persons. The pyramids in
Figure 2, on the
other hand, are all equal in total size in order to better illustrate the
changing structure of the population by age and sex."

Germany || Some
Explanations
The population in both the old and new federal states began to decline in
the 1970s because the birthrate was falling. Since
1990, however, there has once again been a slight upward trend in the
west. With 10.5 births per 1,000 inhabitants per year
(in the western part of the country) Germany nevertheless has one of the
lowest birthrates in the world. The population
increase after the Second World War was mainly due to immigration. Some 13
million refugees and expellees entered the
present German territory from the former German eastern provinces and
Eastern Europe.

A Baby Boom in the Making? [Week in Germany, Oct.10, 1997]
Just in time for the Day of German Unity, the Federal Bureau of Statistics
offered the
best evidence yet that Germany is getting over its post-unification blues.
On October 2,
the bureau reported Germans, both eastern and western, are having more
babies these
days. The number of births rose last year for the first time since 1990,
rising by just
over four percent from 1995 to 796,013.

The increase was strongest - 11.3 percent - in eastern Germany. Births
there had fallen
off dramatically in the wake of unification; the low point came in 1994,
when the
number of births (78,700) had dropped by 60 percent from the
pre-unification level.

According to the Bureau of Statistics, the decline was due in part to the
relocation of
numerous young eastern Germans to the western half of the country and in
part to the
widespread uncertainty prompted by the collapse of the eastern economy. A
turnaround began in 1995, as the number of births rose to 83,847, and
picked up pace
in 1996, with 93,325 live births recorded for the year.
1996 also saw the first increase in births in western Germany since 1991.

The number
of births there rose by 3.1 percent to a total of 702,688.
In announcing the new birth figures, the Bureau of Statistics noted one
continuing
difference between the old and new states. The average age of first-time
mothers
remains somewhat lower in eastern Germany (27.3) than in western (28.4).
